the missing angle would be 17 inches. I am not exactly sure but if the leg a and leg b were calculated with those 2 numbers then the other side(known as hypotenuse) should be 17 inches

Answer:

$E(X) = 1 *0.8 - 3*0.2 = 0.2$

so at the long run we can conclude that the best option is :

A) win 0.20 cents per play

Step-by-step explanation:

Previous concepts

The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.

The variance of a random variable X represent the spread of the possible values of the variable. The variance of X is written as Var(X).

Solution to the problem

Let X the random variable who represent the ampunt of money win/loss at the game defined.

The probability of loss $3.00 for this game is 0.2 and the probability of win is 1-0.2=0.8 and you will recieve $1.00 if you win. The expected value is given by:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And for this case if we replace we got:

$E(X) = 1 *0.8 - 3*0.2 = 0.2$

so at the long run we can conclude that the best option is :

A) win 0.20 cents per play
